Validating a JSP

[Hari Dhanakoti]

Hi,

I am using a sample jsp page to work on the javascript validation. My form components resembles as such...

<c:choose>
<c:when test="${not empty listVal}">
Name display on Page
<c:forEach items="${listVal}" var="adj">
<input type="radio" id="first1" value="${adj.value}" name="first1"/><c:out value="${adj.name}"/>
</c:forEach>
</c:when>
 
<c:otherwise>
You didn't choose any feedback checkboxes.
</c:otherwise>
</c:choose>
 

<c:choose>
<c:when test="${not empty horseVals}">
Horse Desctripion
<c:forEach items="${horseVals}" var="horse">
<input type="checkbox" id="first2" value="${horse.id}" name="first2"/><c:out value="${horse.horseColor}"/>
</c:forEach>
</c:when>
<c:otherwise>
You didn't choose any feedback checkboxes.
</c:otherwise>
</c:choose>

If i access form components as such then it gives alert as undefined.

alert(document.validForm.first1.value);
alert(document.validForm.first2.value);

If i access form components as such then it gives alert with the first component value.

alert ('Radio Val '+document.getElementById('first1').value);
alert('Check Val '+document.getElementById('first2').value);

What should i do for validating the jsp...

hi,

1) there is a loop right so every time same name onlt asigned to the input tag ..so if you want to take 2 nd value use
---------------------------------------------------

alert(document.validForm.first1[1].value);...etc
------------------------------------------------------

2) if you want to use getElementById then you have to set new name for every iteration ...because if you want to use getElementById then field name should uniqu other wise it will give first matching value ........

hint:

  
 
<c:forEach items="${horseVals}" var="horse" varStatus="loop"><input type="checkbox" id="first2" value="${horse.id}" [B]name="${loop.count}"[/B]/><c:out value="${horse.horseColor}"/></c:forEach>
 

  hope  this  helps :)

Hi seetharaman ,

Thanks for your reply.
The above mentioned case works well with checkboxes.
Incase of using the radio buttons i would like to have a unique name to represent.

So how do i handle it in case of radio buttons.
Any suggestions?
